, Be it known that l, FRED S. LEWIS, a citizen of the United States, residing at Port Allegally, inthe county oi McKean and State oi" into pots arranged fortravel along a definite path, the charged pots being transferred to an'A elevatory and moved into cooperation with a blowing apparatus.

. Another object is to maintain an even tem- A perature throughout the apparatus, Whereby the glass is maintained in the desired f molten state'during transit from the tank to the blower.

The preferred' details of construction will be described in the following specification, reference being had-to the. accompanying' drawings, in whichw Figure 1 isa top'plan, partly in section;

'and Fig. 2 is' a vertical section and also showing the blowpipe. in operative position.

' .Refer-ping particularly to the drawings, 1 represents anordinary tank in which the glass is initially brought to the desired molten state. This tank, hereinafterl termed the Hmelting-tank, may be of any desired construction and heated in any desired manner, assuch detail-s form nomaterial part of the present invention.

Arranged ad'acent the tankfl is a housing 2, preferably circular in plan, comprising spaced parallel-.walls 3 and 4 and acap-block 5. The walls 3 and are of usual construction vfor such purposes, comprisingan outer covering of redl brick with an' interior lining of fire-brick. Surrounding the housing is a heatin -ring' 6, commonly .called "checkerwork, which in this particu-lar instance is in open communication'with the checker-Work or the,ine1tingtank, so that "a circulation of,

intense heat is gained about` and indirect .contact with the outer wall of the housing.

Within the housing is mounted a circularvor endless rim or table 7, mounted for moveinent upon wheels 8, arranged for v'travel upon a track 9, fixed onthe iloor oi the hous-A ing, any suitable means being used to cause the necessary travel of the table. table, preferably at equidistant points ciroumferentiallyly thereof, \is arranged a series' of blocks 10,` of stone or rtire-cljay, and 'onl each blockis iixed'or otherwise arranged a receptacle or pot 1l. .A' delivery-spout 12, provided with a cut-oit 13, provides communication between the glass-chamber of the tank 1 and the housing 2, the mouth of thespoutbeing arranged above the plane of thepots 11, so that the operator may fill said .On theA pots in succession with material from the tank. p v

Diametrically opposite' the spoutf 12 the checker-work ofthe housing is interrupted,v

and the outer Wall of the housing isa-provided at this oint with a door 14, adapted to be manual y controlled for raising and lowering in any suitable Way. Adjacent the opening in the housing are arranged verticalv guides.. l15, onl which 1s mounted for' vertical-,move-V The elevator is open at top and comprises four side walls and ay ment an elevator 16.

bottom, the side wall next the housing being 'preferably arranged as a sliding door 17,

adapted for raising 'and lowering as is door 14. The elevation is interiorly of a siaeto receive oneof the blocks 10 and is in com-y munication with a source of fuel-supply, as a gas-tank 18, through va pipe 19. The gas is designed for igr'xition Within the elevator, whereby lto maintain the molten state ofthe glass, as will later appear.

The elevator is supported' on a standard 20, connected directly with a piston 21; ar-

anged within a cylinder 2,2I The cylinder is in communication with'a sourceofpressure, as an air-tank, through a pipe 28,.lead ing into the cylinder below the piston' and controlled by a valve 24. An exhaust-pipe 25, valved at 26, branches from the pressurepipe to permit reduction of the pressure within the cylinder.

' Above the elevator is arranged an endless track 27 on which travels a track-wheel. 29,-

lfrom the hanger of which depends a'v blowpipe, connected with an air-supply by a flexible pipe or tube 30. The connection between the blowpipe and hanger is preferably 5 yielding, `as b the use of' a coil-spring 3l, to

permit a sli., t independent'upward movement oi the lovfpip'e, if necessary.

. ln. operationthe pot 1l e posite the mouth et the spout-is lled -to tie desired extent 1c with the molten glass and the table rotated to bring the-next successive'pot into charging position, the'operation being continuous, as will be understood. As the initially-lilled pot, reaches the door 14 both said door and 5 the door 17 of the elevator are raised, and the block ly carrying the i'illed pot, is forced onto the elevator-floor, the gas in the latter 'of course been previously ignited. lrfressure is admitted to the cylinder 22 and so the elevator moved upward until the mouth' ofthe blowpipe 29 is met and forced into the molten glass inthe pot. The valve 24; is closed and the valve 26 opened, permitting the elevator to descend'. At the same time air under pressure is admitted to the blowpipe. The descent of the elevator leaves a cylindrical mass of glass hangin g' to the' blowpipe, which under the influence of the air may be shaped as desired. Upon the dego 'scent of the elevator to the normal point the glass is cut orf just above the pot therein, the doors laandll' are opened, and the block and pot returned to original position upon' the table 7. The blowpipe, with depending 3 5 mass, may be moved to place of `deposit through use of track 2,7 and a successive blowpipe positioned for use with the next successive pot presented by the elevator.

lt is of course to be understood that the 4o mouth of the blowpipe may be arranged at any desired distance above the norma position of the elevator, so that the length of the mass of glass supported by the blowpipe may be varied to suit the particular occasion.

- The main and important characteristic of the above apparatus is that the molten glass from the time of its discharge from the tank to its engagement by the blowpipe is maintained at an even and proper temperature,

5o insuring the proper and perfectresults obtainable in no other way. i
